I: ting up in substanl'ially sealed conditio semi-solid or past-y substances, such as Vaseline, medicated greases, l'mtt-er, co ics, etc, and for delivering the same mom. the container in any desired uantityv or quantities.-

in its broadest aspect, the f same asthat show-n, m my prior application is.

1 a plication, however, includes more than the application referred to and, While a continu" ation' thereof to Cl*ii'lil subject matter, zillusttates claims improvements on the construction there shown and described.

The object of the present invention is t provide an impro; v

bed. which 101 a FIVGZ] size conta piston containers, and, to contain a given made Another object of the invent-ion is to provide an improved form of container inwliich the piston or follower has extended bearing upon the -".'l. Wall of the container and is steacliec a part thereof, being collapsible nearly complete discharge of the contents of the container.

The invention comprises the construction s guided thereby, the piston or pensive material such irepi'esonts a cptacle or o 1, and shoiymg a diileient form. oi he i YQIliZlOIl; Fig. 3 1s a. new coy-n ionoiw Fig. 1, and showing a modified form cl 5 ton or follower and moving means they and Figs. 4 and simila ovie s shoe other modifications.

In receptacles or containers of the present typeand'employing a piston or follower :1 moving the contents endwise thro container and out of: its disc with the inner wall of the container to stelidy the piston and prevent its Wabbling or displacement under conditions of use Soch a container is sl and described in i prior an 'cation ref-erred to: The e coded T ling of such piston, ho astes valuable s ace Within the cents-oer which, by the present inventio is utilized for increasing the capacity of the container without increasing the size of the same-a The container illustreted in Figs. 1 and 2 is of the same general type as that described in my prior application. It embodies a casing 1 of tubular form and which ma be constructed of glass, icrce a, black plate I some less ex paste or paper board and is shown as formed of the latter.

or tin plate or, ii preferred One end of the receptacle is permanently it closed by a head or cap 2, which may be of any desired shape and cit-her fiatcr cupped and formed of suitable material, preferably thin sheet metal, and is shown as'criinped at its rim or edge to the body of the receptacle. Preferably, centrally disposed in the closure 2 is a mouth or spout 3, covered by a suitable removable cap 4: which may be either threaded or otherwise formed for at tacl nentto and detachment from the mouth or spout, or rotatable thereon to open and close the discharge orifice 4?. The other end of the receptacle may also be provided with; a similar cap or closure 5, also 'crnnped to the wall of the casing, but this may be either a'cord, Wire or flat band and'of metal or other material, as desired; The flexible connector 1s Wound upon a winding shaft 8 which extends transversely across the mouthor spout 3 of the receptacle and through the opposite walls thereof. One end of the windingshaft 8 is bent to form a suitable The other handle 9 for turning the same. end of the shaft 8 is upset or riveted, as at 10, to prevent endwise mt vementof the winding shaft in one direction through the container.

Suitable connection" is provided between the fiexibleconnector-T v and the winding shaft 8. In the form illustrated, this connection is of the type illustrated'in' my prior application referred to and comprises a spring member 11 having its end portions coiled in the same direction around, but in opposite directions along the shaft 8. The free end portion of the flexible connector 'I is passed through the middle portion or loop 12 of the spring 11 and secured to itself, as by riveting or .in any other suitable The spring 11 is so coiled about the shaft 8 that When the shaft is rotated in one direction, the coils of the spring open up and permitfree rotation of the shaft therein. Then, however, the shaft is ro-- tated in the other direction, the coils of the spring grip the shaft and are rotated therewith. v

The piston or follower 6 in the present construction comprises two members, namely, a disk, head or body. 13 and an internal sleeve member or flange 14. These may either be secured together. and operate as. one, as 1n Fig. 5, or may beseparate from each other. The disk or head '13 may be cup shaped, but preferably is of relatively with its outer face closely fitting and slid-- ing along the inner surface or wall of easing l, and is of some length longitudinally of the container. Preferably, one or the other, or both, of the members of the piston is or are formed of some suitable collapsible material, as for example, paste or paper board.- This -matcr1al is so chosen and of such strength as to normally retain its shape,

form during the conclusion of the operation of removing or discharging the contents from the receptacle. One of the members will always be collapsible although both may be so formed, as Will more fully hereinafter appear.

In the form shown head or disk 13 is formed of collapsible material, as stated. .T he sleeve member 14 may be formed of wood, glass, porcelain, sheet metal or paste or paper boardof such strength as to be practically rigid. It will be understood, however, that the head 'or disk 13 ismade of such thickness and of such material as to retain its shape during the major portionof the movement of the but nevertheless not to retain permanent in Figs. 1' and t2, the

pistonalongthe receptacle, the resistance of the grease or other contents of the receptacle not being sufficient to'cause it to bedeformed or to collapse, The flexible connector, 7 is secured to the piston in the manner illustrated in my prior application referred to, namely,. 'by being passed through anaperture 15 in the'center of the piston and through washer 16 mounted against the unders'urface of the. piston. The flexible connector is then turned n upon itself andbent to prevent its-being withdrawn through the. piston. In practice, the washer-161s made of relatively rigid mate-, rial, a's forexample, thin sheet-metahand ofsubstantially the same diameter as the spout or mouth 3 at-the discharge end of the re c eptacle,'but preferably slightly larger than the same, and is somewhatsmaller in d ameter than the inside diameter of the sleeve 14.

In use of the. receptacle described. the

winding. shaft is rotated to wind the flexible connector upon the shaft and draw the piston longitudinally. toward the discharge origages the rear edge 1? of the sleeve member 14-. Consequently, if one side of the head or disk 13 advances more rapidly than .the other, it will strikethe rear edge 17 of the sleeve 1% and be retarded until the head The head or disk 13. of the piston does.

or diskcontacts'at all points on its periphcasing. .l\'l1en the piston reaches the endfof its stroke, the forward edge 18 of the sleeve member ll strikes against the end closure 2, and can'move' n'o -fartlicr. It, moreover, is

of rigid materialand will n ot collapse. At

this point int-he operation, further rotation of the windingshaft S draw s the thinbut:

rigid washer- 16 toward the'd'ischarge orifrom the container.

In the latter case, when the head or disk 13 is formed of .collapsible material, the cupped washer is drawn into the sleeve member ll at the end of the stroke and scrapes along the same to clean itand remove all-grease The cupped washer, however, is not essential with any form of the invention and may be omitted if pre ferred.

Under some circumstances, it may be desirable to construct both members of the piston of the same kind of material and to also connect them together. Such an arrangement is shown in Fig. 5 which illustrates a container of the same construction and manner of operation as that illustrated and de-v scribed in my prior application, Serial No. 674,039 referred to. In this type of recep tacle, the piston is made of two members or cups 30,- 31, arranged back to back and formed of paper,.paste or paper board, or

1 other collapsible material. The cup 31 and the flator disk like portion of the cup 80 form a head or body to which is secured the sleeve or flange 32 of cup 30. The piston is moved by a winding rod or shaft and flexible connector connected to a washer on the I rear face of the piston and all of the same type and construction as the same parts shown in Fig. 1. \Vhen the piston described reaches the end of its stroke, it collapses, in the manner shown in Fig. 5, between the .rigid washer and the end closure 3.

The forms of container.illustrated and described all conserve considerable space and save weight Containers of this type are made as cheaply as possible, and the cheapest form of piston is probably that formed of a solid block of wood.v In a container having a diameter of 10 inches, the piston, if formed to have sufiicient bearing lengthwise of the casing-must be about 8 inches long, and if made of wood will weigh several pounds. lVith the construction described, not only is the volume or space occupied by the piston used to increase'the capacity of the container. but the package is made lighter by decreasing the weight of the piston. The forms shown may be constructed and. formed throughout of inexensive material.
